Blast City PSU is the oldest of them all, so no wonder it's performing the worst. Give it five years and your SUN PSUs are going to perform just as badly.
If you were local to me, I would absolutely do it for you. It's like a 15 minute job with a desoldering tool.2. I'd love it if you re capped the PSU on my blast that would be very cool of you
Don't tell me they're all powering their setups with a Capcom IO.My PSU and many of my friends with blasts cannot power a full net dimm set up and I wouldn't recommend trying it.
